In order to manage forest ecosystems at a sufficiently high biodiversity level it is necessary to study the ecological, structural and production characteristics of virgin forests. The research was directed towards identifying the characteristics of mixed fir and beech forests (Abieti-Fagetum s. lat.) in the area of the strict reserve of the National Park Biogradska Gora in Montenegro. Basic characteristics of these forests were researched in the process of definition of forest types. In this manner, it is for the first time that a realistic base for typological management of forests and forest ecosystems with similar ecological and structural characteristics was provided for the specific sites.

Ecological Changes

Understanding of the natural factors that lead to complex changes in forest ecosystems is limited. Worldwide, there are only a few forests as pristine and isolated as the Sierra de La Laguna in the southernmost range of the arid Baja California, Mexico. Its outstanding trait as a model system is that anthropogenic stressors are notably absent, which facilitates the study of natural ecological processes of the forest because separating human-induced ecological changes from natural ones is not a simple matter. In this study, we sampled sites and defined vegetation units on the basis of dominance of the canopy by the main tree species. We identified three forest types: the pine and encino forests that occupy the higher areas and the roble forest at lower elevations. For each living tree in the sampling plots, we measured height, canopy coverage per tree, diameter at breast height, as well as the amount of deadwood, leaf litter, and abundance of young trees. A succesional competition occurs between Pinus and Quercus sensu lato; we conclude that the encino forest represents a climax condition, the pine type represents an early succesional stage, and the roble forest type is a simple climax community.

An in-depth understanding of the dominant factors controlling soil respiration is important to accurately estimate carbon cycling in forest ecosystems. However, information on variations in soil respiration at different soil depths and the influencing factors in forest is limited. This study examined the variations in soil respiration at two soil depths (0–10 and 10–20 cm) as well as the effects of soil temperature, soil water content, litter removal, and root cutting on soil respiration in three typical forest types (i.e., Pinus tabulaeformis Carrière, Platycladus orientalis (L.) Franco, and Quercus variabilis Bl.) in the mountainous area of north China from March 2013 to October 2014. The obtained results show that soil respiration exhibited strong seasonal variation and decreased with soil depth. Soil respiration was exponentially correlated to soil temperature, and soil respiration increased with soil water content until reaching threshold values (19.97% for P. tabulaeformis, 16.65% for P. orientalis, and 16.90% for Q. variabilis), followed by a decrease. Furthermore, interactions of soil temperature and water content significantly affected soil respiration at different soil depths of forest types, accounting for 68.9% to 82.6% of the seasonal variation in soil respiration. In addition to soil temperature and water content, aboveground litter and plant roots affected soil respiration differently. In the three forest types, soil respiration at two soil depths decreased by 22.97% to 29.76% after litter removal, and by 44.84% to 53.76% after root cutting. The differences in soil respiration reduction between the two soil depths are largely attributed to variations in substrate availability (e.g., soil organic content) and soil carbon input (e.g., litter and fine root biomass). The obtained findings indicate that soil respiration varies at different soil depths, and suggest that in addition to soil temperature and water content, soil carbon input and dissolved organic substances may exert a strong effect on forest soil respiration.

Sample Points

The occurrence and duration of concrete frost were observed at 28 forested sites along an elevational gradient on a New Hampshire mountain. The presence of concrete frost was determined with an aluminum probe on 17 dates between November 1973 and June 1974. Concrete frost was found at all sample points in soils of coniferous forest ecosystems above 950-m elevation from mid-November to mid-May; some concrete frost remained into early June. Concrete frost occurred at most sample points in soils of transition zone forests that were composed of mixed hardwoods and conifers for 4 months, in soils of northern hardwoods forests for 2 months, and in soils of successional fir stands at low elevations for 4 months. Winter weather conditions and differences in leaf litter insulation probably accounted for the variation of soil frost beneath these forest types.

The aim of this study is to assess the relationship between geological background and habitats of mushrooms. The study area is Grevena, a Prefecture of Greece well known for the great variety of the fungal flora and its distinctive geology. Thematic maps of the study area were produced with the use of GIS, taking under consideration geological formations, elevation, ecosystems and land use. Findings provide evidence that certain mushrooms are more likely to be found in specific ecosystems. The connection between forest ecosystems and the geology of the study area is more apparent, as certain forest types are related with specific geological formations; due to the insignificant presence of grasslands and riverine settings in the study area, it is not possible to assess the role of the geological formation for these mushroom habitats.

Invasion of synanthropic plants into the forest vegetation of the Cedynia Landscape Park (NW Poland)The distribution of synanthropic plants was studied in the Cedynia Landscape Park (Cedyński Park Krajobrazowy), with particular reference to alien species and their capability to penetrate into forest ecosystems. The research was conducted by the cartogram method in the Atpol system (1-km grid squares). The Park is situated within the Western Pomeranian Province and includes two large woodland complexes: the Piasek Forest (Puszcza Piaskowa) and the Mieszkowice Forest (Lasy Mieszkowickie). The forest vegetation is exposed to various forms of human pressure. Results of this study show that the vascular flora of forests of the Park is composed of 609 species: 506_native taxa (277_non-synanthropic spontaneophytes and 229_apophytes) and 107_anthropophytes (49_archaeophytes, 48_kenophytes, and 9_diaphytes). Most synanthropic plants in the studied forests occur near roads, cottages, and river banks. Contributions of various historical-geographic groups to the total number of species varied between forest types, but apophyte species were usually most numerous. In contrast to some earlier reports, not only alien but also native species were found to be more diverse near forest roads than in the forest interior. Spontaneophytes are equally diverse, while apophytes are much more diverse near roads.

Voluntary forest certification is a widespread mechanism of a market economy aimed at balancing economic, environmental and social interests. The article provides a methodology for identifying representative areas of forest ecosystems when forming a network of protected areas that form the ecological framework of the leased area. As an example, we took a logging company that leases two forest plots in Chebulinsky forestry of the Kemerovo region with different characteristics of the forest fund and the history of forest use. Based on the basic requirements of the current FSC forest management standard, a methodology for identifying representative sites has been developed. As a result of its application, it was found that in the area with more intensive forest management, 41% of the forest types present in the entire forestry area are found, despite its smaller area (3837 hectares). It is 21% on a larger, but less transformed and fragmented plot (5224 ha). It was revealed that the share of the frequent forest types (with the occurrence above 1%), which is 18%, is common for both leased plots. The area of representative plots is also approximately the same - 4.16 and 3.79%, respectively. It is noteworthy that frequent types of forests are already present in sufficient quantities in the network of protective forests and especially protective areas in production forests. But rare forest types, as a rule, are slightly represented in them. It enables us to conclude that it is important to form a network of representative sites in forest certification. It has been established that both coniferous and deciduous stands fall into rare forest ecosystems. The average area under allotment in the older cultivated leased plot is 8.8 hectares (with a variation from 0.8 to 55.0 hectares), and in less cultivated - 13.3 hectares (with a variation from 1.8 to 28.7 hectares), which is quite logical. However, in the first leased area, only 9%, and in the second - 6% of representative areas have an area of over 20 ha, which is accepted as a threshold in several countries
